[Feature Request] Allow players to configure X-Real-IP Header so that the regional restriction of Netease Music can be unlocked

[appe233]

I'm now using the fabric version mod with mc 1.20.1. Since I'm not in the mainland most of the pieces just refuse to play. A method I used to use is appending a HTTP header "X-Real-IP" to the requests.

I tried using the same trick here by adding a new line in src/main/java/com/github/tartaricacid/netmusic/api/NetEaseMusic.java

In init()

requestPropertyData.put("X-Real-IP", SOME_IP_FROM_MAINLAND);

The trick worked, so I think it would be good if this feature can be added to the mod itself. (I know zero java and just copied the former line)

Looking forward to a more standard implementation!

I plan to add a configuration file that allows adding custom request headers.
When we are finished, please try to see if it works.
